BEGINNER | Quick & Easy Calibration VIDEO General Information Brightness BLACK LEVEL Video Connections First, you need to know how your display is connected to your system. For High Definition systems, you may be digitally connected with HDMI or DVI. This will provide the most accurate signal to your display. For analog systems, you may be connected with VGA or Component cables. These are capable of HD resolutions but will not provide the best HD image accuracy or experience.
BEGINNER | Quick & Easy Calibration VIDEO The visibility of the brighter steps indicates that subtle detail in shadow areas will be visible while the absence of the darker steps shows the monitor’s ability to display true black is being fully utilized. A monitor adjusted in a dark room will appear too dark when the room is lit. A monitor adjusted in a lit room may appear too bright in a darkened room. Perform these adjustments in lighting conditions typical of the normal viewing environment.
BEGINNER | Quick & Easy Calibration VIDEO Aspect Ratio Native television aspect ratio is set to 4:3 for older SD (Standard Definition) displays and 16:9 for common HD (High Definition) systems. This means that no matter what the screen size, the display area will be 4 units wide by 3 units tall for SD monitors and 16 units wide by 9 units tall for HD monitors. The units can be anything: feet, inches or meters.
BEGINNER | Quick & Easy Calibration VIDEO Player Setup ray™ player that affect the display type. Set this control to match the connected display, in this case 16:9 (figure 7). Display Setup Mismatched Equipment 8 Set your Blu-ray™ player’s aspect controls to output a 4:3 image instead of 16:9. The Blu-ray player will likely apply a “letterbox” correction to the images.
BEGINNER | Quick & Easy Calibration VIDEO In the image below (figure 13), the blue sky should appear deep and natural. If it appears to be washed out, bring the color level up slightly. This image should be colorful and lifelike. If the color and tone are set properly, then the variety of colors should be clearly different and complementary (figure 14). You may wish to move between these images making small adjustments to color until you are satisfied with the picture’s accuracy.
BEGINNER | Quick & Easy Calibration VIDEO/AUDIO Viewing Angle CRT Purity 12 Observe the screen for color purity deviations. The entire screen should be a solid magenta color that is mixed from pure red and pure blue. Change your viewing angle to see whether looking straight at the screen, sitting off axis, standing or changing the viewing distance affects the appearance of the pattern. Ideally, there will be no change in hue or intensity within reasonable viewing angles.
BEGINNER | Quick & Easy Calibration AUDIO The Polarity test will begin using the left front and right front speakers only. It will advance around the system in a clockwise pattern. Each test will involve two speakers only. The test will end with the left front and center speakers. A test signal will emanate from each pair of speakers. The signal uses a broadband energy that covers the entire audible frequency spectrum.
ADVANCED | Premium Calibration Tools Monitor Selection Each tone will repeat until you advance the test by selecting the on-screen menu button to proceed to the next sweep tone. Caution – you should be aware that sweep tones, especially at higher frequencies, can cause hearing damage. Extreme care should be used with these tests, especially when small children or animals who are more sensitive to high frequencies, are present.
ADVANCED | Premium Calibration Tools Monitor Selection Advanced Contrast Test Overview White Checkerboard This moving test pattern (figure 20) is designed to fine tune the contrast level of a display system that affects the maximum light output from the display. It consists of a super white background with an overlay of geometric shapes of different brightness levels.
ADVANCED | Premium Calibration Tools Monitor Selection Convergence Test (figure 22)* Crosshatch Display This test pattern (figure 22) is a regular grid of squares. There are 16 squares horizontally and 9 squares vertically, corresponding to the aspect ratio of current HDTV equipment. This pattern is most useful for direct view CRT monitors or projection systems that require the registration of multiple image sources. white grid without color fringes.
ADVANCED | Premium Calibration Tools Monitor Selection Chroma & Hue Keystone Linearity Pincushion Skew This modified industry standard test pattern (figure 25) contains examples of the three primary colors, the three secondary colors, 75% white as mixed from the primaries, ideal black and ideal white. A PLUGE signal (Picture Line Up GEnerator) integrated into the pattern also contains super black and super white signals for monitor setup.
ADVANCED | Premium Calibration Tools Monitor Selection Hue or Tint Adjustment Locate the display controls affecting “hue” or “tint.” Using the blue filter, observe the main color bar samples of cyan and magenta. Directly beneath those are reversed samples of magenta and cyan. Adjust the hue or tint control to balance the levels of the main color bars with the samples on the reverse strip. The hue or tint is now properly adjusted.
ADVANCED | Premium Calibration Tools Monitor Selection difference between ideal white and ideal black contained in this test pattern to match the display capability of the monitor. Contrast mostly affects the white parts of a video image but will also affect the dark areas. The Brightness adjustment sounds like it should set how bright things are on the screen. Instead, Brightness is set to remove residual light output when true black is present in the video.
ADVANCED | Premium Calibration Tools Monitor Selection Room Lighting Conditions If your room lighting is relatively dark such that these settings create an image that’s too bright, you may reduce the Contrast setting to create a more comfortable picture. The Contrast control actually sets how white the whitest object is on the screen and may be adjusted downward to prevent an overly bright image.
ADVANCED | Premium Calibration Tools Monitor Selection amount of sharpness will add some desirable definition to the image as shown in the center sample. Adding too much sharpness will begin to add undesirable edging artifacts as seen on the right hand sample. Overscan Test (figure 33)* The extreme edges of a video image are generally hidden from view by either physically masking the borders with a bezel or by scaling the image up electronically to push the edge of the image off screen.
ADVANCED | Premium Calibration Tools Monitor Selection Read the percentage of overscan directly from the edge markings by determining which percentage line is the first one unmasked (figure 35). The readings should be uniform on all four sides. If the readings are not uniform, the image is not centered on the display area. Direct View Most direct view CRTs will exhibit some form of CRT Displays overscan. The percentage of overscan may be read in the same way as a digital display.
ADVANCED | Display Evaluation Tools Monitor Selection cides with the “zero” marks. Watch the markers (calibrated for both television frames and milliseconds) and listen for the tone to emphasize exactly when the zero markings light up yellow. Adjustment If the emphasized tone and zero markings appear to coincide, your audio delay is probably in good alignment. You can double check by watching the markings before and after the zero markings.
advanced | DISPlAY EVAlUATIOn TOOlS Monitor selection aDVaNCED sCaLING tEst 1 From a distance, the monitor may appear to be flat grey. looking closely, however, you should see the individual checkerboard squares as shown in the inset. This condition is only possible in systems that are digitally connected and do not scale the image (figure 41).
ADVANCED | Display Evaluation Tools Monitor Selection blurring If your connection to the monitor is analog, you may also experience additional blurring. For best results, use digital connections throughout your entire video system. Advanced Scaling Test 2 Alternating Vertical Pixels This pattern is a variation of the One Pixel Checkerboard using only the alternating vertical pixel component (figure 46).
ADVANCED | Display Evaluation Tools Monitor Selection test signal. Some amount of aliasing is normal due to the limitations of video systems. However, irregularities in signal processing or display technology will show themselves using this pattern. extreme artifacts or aliases, you may also see other impairments on program video. Consult a service technician to diagnose and find a possible solution to the problem. Below are several examples of what the hyperbolic zone plate may show (figure 49).
ADVANCED | Display Evaluation Tools Monitor Selection the left below “Ideal Black” begin to blend into the background. The residual brightness is most easily set in a darkened room but should be adjusted in room lighting typical of the viewing environment. The top band of the test pattern is used to adjust contrast to achieve the desired white levels relative to room lighting.
ADVANCED | Display Evaluation Tools Monitor Selection Reading Gamma This test chart (figure 54) consists of a fine grain black and white checkered background, which should appear flat grey from a distance. Our eyes will average the black and white elements together to approximate 50% grey. If you are using a digitally connected flat panel display, this chart will only work well if the display presents a pixel accurate 1920x1080 image without overscan.
ADVANCED | Display Evaluation Tools Monitor Selection Compound Test Chart As a quick reference, this chart (figure 57) embodies many of the patterns found elsewhere on this disc. It also contains unique patterns used for checking display response and alignment. (figure 57)* Components It is not intended to be used as an ultimate setup tool, rather as a “status at a glance” to quickly check a display device for proper operation.
ADVANCED | Audio Set Up Tools the horizontal wedge (figure 62) is calibrated in TV Lines. These indicators are intended for analog connected devices. While the readings are subjective, they are useful in quantifying basic system performance. (figure 62)* Sharpness setup blocks are included to assist (figure 63)* in adjusting aperture correction or sharpness found in most display systems (figure 63).
EXPERT The band of pink noise generated by this test is specifically directed to the LFE Channel (low frequency effects) and will help you position your subwoofer to the most desirable location in your listening environment that will allow you to get the maximum volume without distortion. Once this position is located, often in or near a corner, select the phase setting (if one is available) for maximum volume without distortion.
